Looking for cummins swap help

Ok so everyone knows iv been going back and forth on keeping my burb. But I think I do want to keep and I really want to cummins in there. Iv looked around so I know the info is out there but I guess I dont know where to look. Seeing as how we are in texas and someone id always willing to anser a few Q's I figerd I would just ask.

1. Can I use my chevy drive train? (if so how)
2. Does it just bolt in?
3. If not do they make a motor mount kit?
4. What is a 4BT and is that a better motor for my burb?
5. What kinda wiring will there be?

Thanks for any and all help here guys.

Yes you can use chevy drivetrain.

Yes & no. Most stuff will bolt right up with the right adapters.
You will need to do some fab work.

Search crewcab59 he builds motor mounts for them.

6bt is a 6 cylinder, a 4bt is a 4 cylinder. The T stands for turbo.

Wiring depends on what motor you use, older 12 valve = easiest.

Do alot of reading first.... It will save you money in the long run.

Good luck & keep us posted.

The more I look the more I see it will cost a arm and a leg. I dont think I can aford to do this swap.

I want to keep my truck but what can I do to get better mpg out of it.

Will a intake, headers, and a cam help or hurt it?

If your wanting a diesel for better mileage, you could always swap in a 6.2 or 6.5 Would be alot cheaper than a cummins and I think they get better mileage than the cummins.

Is there a better gas motor I could swap in? Or maybe taking my motor to tune port? Something...

I'm assuming since its an 87 its tbi, check out http://www.tbichips.com/truckmods.htm He recommends mods for power and mpg. He also has good chips to help. I run the hot chip in my 95 and noticed power and mpg increase, he also has a mpg chip.

Consider, whatever money you spend on the engine swap could be spent on fuel. Lots easier to add fuel. For instance, if you spent $100 on the swap, how many more miles could you drive? You're only going to save the difference in fuel mileage, which would take a long time to payback the swap.

probably won't see enough of an improvement to cover the cost of those upgrades. What gear ratio do you have and what size tires? If it were me I'd consider changing gear ratios or swapping axles that have lower gears, tbi spacer, free flowing muffler, full tune up, k&n filter, and mpg chip.

lilblue_150 just gettin started
I agree with michael0584 doing an intake and headers and all that you wont see enough diff. in your fuel mileage for the cost search for randys ring and pinion and he has a calculator on his site put in your stock gear ratio you original size tire and the size tire you have now and he has a chart that will help guide you to finding the rite gear ratio to help you with fuel mileage trust me gearing helps give you power back plus fuel mileage with bigger tires I have a 93 f-150 4x4 I put 4:10s in the stock was 3:55 I have 6" lift with 33" nitto mudgrapplers the 4:10 was a little over kill shud have went with 3:73 for normal DD but went 4:10s for higher rpms at higher speeds instead of running at 1800 to 2000 at 70 I run 2100 to 2300 did it for towing.
